: Prestone coolant question

03-17-06, 07:55 AM
I use that green prestone (yellow bottle) that says it can be used for any year and model or color. I am assuming that this is already premixed or should I still add water to it?

It's only pre mixed if it says it on the bottle somewhere. Otherwise you have to add water to it yourself.
